- Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)
- Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)
- OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby]

+ - Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows.
- Demo: Added basic Drag and Drop demo. (#143)
- Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section.
- Examples: Tweaked the main.cpp of each example.
